BAKERSFIELD, Calif. (KGET) — Liliana Carrillo, the “prime suspect” in the killing of her three children in Reseda last weekend, spoke to 17 News from the Lerdo Pre-trial Facility on Thursday.

Carrillo spoke to 17’s Eytan Wallace, admitting that she killed her three children. She believed their father was involved in human trafficking.

In the interview, she discusses her upbringing and how she met the children’s father, Erik Denton.

Carrillo and Denton, were involved in a bitter custody dispute. Denton was supposed to see the three young children last Sunday, the one day every other week that he was allowed to be with them.

Three-year-old Joanna, her 2-year-old brother, Terry, and 6-month-old sister, Sierra, had been staying with their mother — Denton’s ex-girlfriend — in Reseda. Fearful for their safety, their father had petitioned the court for custody March 1, alleging their mother, Carrillo, was delusional and had taken the kids and refused to tell him where they were.

Authorities say the children’s grandmother had called police last Saturday morning after the discovered the children dead at an apartment in Reseda.

Kern County prosecutors allege later that day, Carrillo drove through Kern County where she allegedly carjacked one person. She was later arrested in Tulare County.

Carrillo has not been formally charged in the murders of her three children in Los Angeles County.
